wall hanging structures 22), and it is not limited in preferred
embodiments above-mentioned. Preferably, the positions of the
fixing portions 203 are the same as the fixing portions 203 of the
wall hanging structures 20 of the LCD device above-mentioned.
[0048] Hence, by efficiently sharing a part of weight of the LCD
device to the side edges of the LCD device through the side
connecting portions of the wall hanging structures, the wall
hanging structures and the LCD device according to the present
invention can improve the mechanical strength of the wall hanging
structures of the LCD device, and decrease the stress deformation
of the back plate of the LCD device, so as to decrease the
influence to the display quality of the LCD device.
